It is the "Stock Exchange" centre of groups. Basically all groups who choose to join it can have their group stocks sold to investors. The price of their stocks will change daily depending on how valuable the group becomes or how much activity occurs in that group. Check it out:

What exactly is it?

Are you interested in putting your group "Team Plasma" into the Smogon University Stock Exchange?

Very well, alliance accepted. Thank you for the referal.

Understood
Do you agree to the alliance? If so I'll let you join a group truly dedicated to the safety of other groups every major leader is in this group... Team Harmony

Alright, I guess it will be a "crash and burn" experience then. If our group does fail to expand and become successful (which it just might as many small groups inevitably do) then it will fail. If it does somehow succeed and expand significantly than even better. Whatever the outcome, I will continue to maintain and keep our group for the few who do enjoying being in it.

I have no problem making the alliance I'm just stating my concerns

Have we been bothering any groups in this forum? Name a group we have caused trouble with? I don't understand your problem with us. I am not trying to sound intimidating in any way. I am simply saying leave us alone and if we aren't causing you trouble then don't bother us, unless you plan on making an alliance, which I do not see happening in the near future with you.

Failed groups moving to Smogon dont concern me iv prepared for this and have a Mod who agrees with me in all aspects.
I think you may have the right idea but it will fail most groups dont need this and want to be left alone
As scary as a group of less then 20 sounds ill take my chances

Almost every essential, well populated group failed on Serebii and many of them have come here to start anew too. BTW, so far we have made more alliances than enemies since our commision. as a matter of fact we have NO enemies. So long as we are not messed around with, we are not an aggressive group.
