First of all,
I have to say I like the joomla module extension LastPhpBB3. It´s easy, works without any problems and it is also according to my opinion clearly programmed.
But of course everything can be improved and therefore I´d have one question. Would be possible to implement such feature like to display just topics from last X (e.g. 30)days? It´d be great. Just one additional param in back-end.
If you don´t have a time for that, I´ll definitelly implement it for my use. If you´d like I can provide it for you also. But I don´t wana to start with this changes before you say to you don´t have a time for that.
