I tried to add a new gear for "other" activities and after I'd entered the name GC logged me out. I have no idea how to work this around. Checking the "remember me" box did not help.
I've found out that after inserting a copied text "Unihoc UNITY Curve 3.0º STL 26", it logged me out. Inserting "Unihoc UNITY Curve 3.0 STL 26" (without the degree symbol º) was OK.
