I am not sure about the one that was listed @mods, however, we will be having an official version called: phpBB2XL which will be headed up by myself. Once all the hub-bub of the site smooths over I will begin active development of it.
I expect about a week or so until I get something released.
The initial version will have a half-dozen or so of the already 2.0 Compliant MODs.
We will have a category here @ phpBB.com/phpBB/ (We did, but it was removed to keep confussion down) once I get into development of it.
If you (or anybody else) is interrested in developing it, just send me a PM.
I am going to keep the development team of phpBB2XL to around four (4) people... so if you want to be involved, you'll have to present your experience. <smile>
