Adding an FAQ plugin

Hello,

I would like to add an FAQ page to my site and have been looking at various plugin options for doing so – I wanted a little advice before installing one to test.

Several of these plugins mention that they use custom post types, and I was wondering if the fact that GD uses CPTs too would therefore lead to incompatibility (or whether it is simply an issue of names of CPTs etc determining incompatibility)?

Taking this further, if I were to install a plugin that used CPTs for FAQs and it did cause problems, would just deactivating and removing the FAQ plugin undo the damage?

Finally – I would be happy to hear if anyone is successfully using an FAQ plugin, and if so, what it is.

Sorry if these questions sound naiive – I am not fully tech-brained-up.

I am using GDF Modern Child and have buddypress and BBpress installed (plus various other plugins)

Thanks
