looking for server to play-cz/sk community

Hello I would like to ask you. Are here some cz/sk clans, or which server is playing the most cz/sk community on? Thank you.

There is a polish clan on Magmeld, if that counts.
Other than that, your best bet is probably chronos..

Make a lvl 1 character on each server and open the Clan Entry window (the icon with the two reddish flags in the lower right corner of the screen). In the "Introduction" column all the way on the right you can quickly see the clans' nationality. On Naia there is for example NightHawksCZ explicitly listed as CZ/SK clan. On the same server there is also the RejzovoKlan, which is mainly czechoslovakian but doesn't seem to actively recruit at the moment. Both clans have been around for a long time, so they seem to be doing not everything wrong :)

Ok, thank you very much :)
