I have decided to take a step back from phpBB development.
I have enjoyed learning the first steps of writing my own extensions, but my studies must come first.
Once I've completed my degree I'll re-evaluate how I can be involved.
You can find my phpBB extensions on GitHub -do not use them on a live environment- as they failed validation, but feel free to continue their development under the GNU General Public License v2.0.
Thank you for your support.
