The add-ons that need to be moved over are:
1) AutoMark: viewtopic.php?t=52486
2) Compass3D: viewtopic.php?f=66&t=53852
3) OverheadFonts: viewtopic.php?t=53330
The others such as DisableCombatLog, PlayEffectsOn and RetAlert are already on Idrinth's site and someone else is now maintaining Pocket Palette.
Additionally, there's a couple of random demos and useful macros which will also be lost when the account gets deleted. The full list of everything can be found here: https://github.com/Zomega-WAR/AddOns/
I'll be deleting the GitHub account in 7 days which should give enough time for someone with a working account on Idrinth's site to move them over. If they're not moved after that point then RIP (I'm sure lots of people would like to see AutoMark vanish
