Forum plugin that's compatible with MultiDB

We're looking for recommendations on an attractive and functional forum plugin that is compatible with Multi DB.

We were using Simple:stuck_out_tongue:ress but got an error message that it couldn't write tables anymore and then read that it wasn't compatible with Multi-DB.

Any recommendations?

Also, will we potentially see other plugins have errors now because of MultiDB?

We didn't see anything about it causing problems when we installed it so this is all new.
