Small corps are absolutely welcome in nullsec. Please contact me ingame to discuss getting your small corp set up in Vale of the Silent.

On a more serious note: a larger entity would rather have a couple of guys dissolve into the larger structure (and apply to existing corps) to keep a strong sense of unity and direction. A large alliance with lots of small corps that each operate 'on their own island' is less attractive then a formidable unified force which can take, and hold, strategical locations.

Why can't my frigate do L4s

I agree with that.
But why a corp with.. lets say... 200 members, can take and hold a system and 10 corps with 200 members in total can't ?

Big alliances don't accept small corps as their members. So they said it in a way... Maybe they think differently.

Who is the cow and what is the milk ?

Yeah, all those < 10 member corps in the rental alliances are there as show. Oh, you mean you want to live in null, but not have to pay to live there, or contribute in any way, or have to deal with defending your space, or really anything else. You might want to consider just finding a quiet wormhole and living there instead.

The cow is a bull and that isn't milk your drinking....

The better question is why do you want to go to null? I jumped out there to an old clone and slowly made my way back to lowsec 18 jumps through systems only populated by drag bubbles. Null sec populations tend to be very centered around systems with stations. I can get more action almost instantly living in low sec without the annoyance of being dragged 100 km off gates or having to bounce planets to avoid it. Null bears also are generally skiddish about pvp unless they have the mongol horde at their back so even when you can get fights you have to work at getting them to isolate one or two that you can shoot.

If your just looking for minerals/ratting without the pvp, why not rent? Its not like your short of your choice of rental alliances at the moment. All of the pleasure and not (much) of the pain. Just the shame of being called a pet on the forums

You can always rent. Just as good as owning territory except without all the alliance politics BS.

When CCP finally fixes the billboard code to allow players to add their own pictures, you can gurantee you'll see a :frogout: over every gate in Deklein. It's an effective mean of keeping people away.

Because you don't know that frigates can't handle L4 missions ?
Learn the game first :P

Ive done a L4 in an incursus for the hell of it.

So you CAN do it.

Who is the cow and what is the milk ?

personally i don't have the patience.

Like i write above that... I thought renting is prohibited to small corps. No ?

Quite interested about this concept you have about null and the fountains of isk.
What would you do there that doesn't require going to hi-sec to make the profit? Let me preempt your answer.

If your corp are miners - the ore you mine must be sold - in hi-sec. How are you going to get it there?

If your corp members are into production - how are they going to sell their goods? In hi-sec of course - refer to first question.

If your corp is into pvp - how will they sustain a ship destruction and reimbursement scheme without having a isk making capability and subsequently purchase ship capability from... hi-sec.

So that leaves you one possibility. Null sec Pve. All the pleasure of lvl4 missions with twice the risk.

Have you really thought out this desire?

Now, this is a situation that CCP have made that is ONLY addressable by joining an alliance. So bite the bullet.
