The current forum software is outdated and not suitable for mobile devices, and it is unfortunately very difficult to use on them. Due to its age there are also no themes for mobile devices. We have been since a long time planning a move to a more recent forum software with a mobile-friendly theme. Based on the availability of database conversion scripts for our board, the current candidate is SMF, which seems to have a good selection of responsive themes, too. Our host has recently installed an updated version of PHP, so now we meet the minimum software requirement for the new forum. We'll keep you informed about any update.
