Features for every occasion
IP.Board is undeniably feature packed, but we've been careful not to overstep the line between feature-packed and feature-overload. It'd be easy to gratuitously add feature after feature and push out a new version, but that would be doing a disservice to the thousands of communities that use our software. Instead, we only select features that will make a significant difference to your community and you!
