Installing Hacks (Templates Question)

[StrykerContact]

Ok well I am a noob to installing hacks, it seems pretty easy, but none of the hacks I install seem to work. I have attempted installing:

Quick Reply with open/close switch
Clan Hack

Clan hack only works in my admin cp, but the in forum functions don't even show up.

Quick Reply does not even appear.

My question is when it ask for you to add templates and edit templates, do you need to do this to all the templates for each theme, or just the default template, or what! Help >_<

I think you have confused template with style or template set. As far as your templates, you need to add and edit the templates in every style, or they will only work for that style. If you need help please contact me.

I think I get it now, I still can't get clan hack to work but I think I just made a typo, but quick reply is up and running. Thanks.
