After we had to see at last year, which did not go so well with the development of SMF 2.1 and our suggestions for improvement and troubleshooting go to absolutely deaf ears, we decided to develop our own forum (on the SMF 2.1 basis) and add some options - which we find good.
Furthermore, this forum (of course) also contains our Portal System, which is fully integrated and can be activated or deactivated with one click into the Admin Settings.
Also our SEF System is integrated, which can also be activated/ deactivated with one click. The old SMF caching we have completely rewritten and thus runs now clean and effectively.
We have continued to incorporate many new and advanced features, as well as all the errors we found in the SMF code (there were a lot of them).
