I wrote a comment on the forum, and after submit I noticed a typo. I corrected it and logout.
If visit this forum discussion without login typo is still there. http://i.imm.io/195Hd.png
But if I logged in, there's no typo. http://i.imm.io/195GX.png
upd: test it on this comment. It's Ok, changes appear regardless of login/logout. But case with sea/see is still there
