Limited amount of forums

[Samppa]

Seems that amount of forums is limited to approx. 1000. I´m building a huge board which needs about 5000 different forums :alien:

There must be a reason for this limit. What would that be and what kind of risks a board with huge size brings on?

Is there possibilities to remove this limit or do I have to join a number of forums to one -> this would also need some modification so that all forums would use same user db, navbars would work as in one board etc.

Any ideas?
