Do I need to connect 50 times, because I have visited the site at least 1000 times and nothing ... Firefox remembers my password so I logged only 3 times.

Same here ,,,visited KAT.ph hundreds times... Not even RARE GUEST achievement.
Please someone explain this and how to do this..

i always thought that to get this i should be a member here for at least 50 days but strangely i saw someone joined 4 months ago having the 200 visits achievements thus proving that there is a bug because i have a very bad habit of signing out & clearing up the whole browsing history after each session and i sign in everytime i have something to download/upload/just chat, which is definitely more than 50 visits
