Valhalla + Phalanx are both good clans....
Hf sucks though... not just saying that i've actually war'd them on multiple occasions
not going to lie Hf is pretty lame.. when i was with mayhem makers we swept them for as long as i could remember.
#Phalanx
#Valhalla
end all its your choice and people have there reasons just throwing suggestions out there for you ^_-.
Also for your problem have you confirmed your email from them, Possible go on there teamspeak and talk to someone or try posting an introduction on there somewhere first (alot of clans require a post count on forums to apply usualy only like 25+ just to ensure users are active within the community.)
^if this doesn't work i would suggest going to there IRC and asking a OP.
Hope i could be some help.
