Currently it is set to 6.00 KiB, which is really tiny for a avatar.
Maybe 50KiB?
Also ever thought of adding categories to the forums?
Would make it much easier to find stuff and its quite easy to implement in phpBB.
Ex.
=General=
-Talk
-News
-Offtopic
=Flight Controlers=
-Rabbit
-Naza
ect
=Multirotors=
-Quads
-Hex
-Octa
-BuldLogs
-Settings
=Otherstuff=
Clasifieds, ect ect
Just a suggestion, might make it easier and faster to find stuff.
Thanks for the great forum so far, love it

(I use to know phpbb quite well so shout if I can help with anything)
