I noticed a few things while I was signing up. Not sure you'd call them bugs but possibly just lower functionality/cosmetics.
- When adding tags, some languages are not capitalized. i.e.: drop down menu lists "spanish" and "french" instead of Spanish/French.
- The "Save" button on the Basic Info, Profile, and Language & Communication pages are three different images. Lacks continuity.
- When selecting languages, I hit 's' on my keyboard to jump to Spanish, but it remains on "Afrikaans" because that has an 's' in it. Likewise if I hot the 'f' key to jump to French, it would stop at "Afrikaans" again!
