How to Easily get Froend n need achivement

i donate giants to inactive clans but im wondering if there's a clan with a donation contest or something.

Maybe the 'clan talk' sub forum would be a better place to look.

Search and join a "Max Donators" clan (if they let you). There are several and their intent is to let ppl join, receive troops then leave. If you don't have lvl5 or max troops you may have trouble joining one of these but you could always start your own :) GL!
