Can I participate up to 2 Guilds ?
Yes and no.
Yes in that yeah you can be in up to 4 guilds at once.
No as in you can only represent one guild at a time (but change who you represent as often as you like), and only the guild you represent you can see the guild chat of, gain influence for and basically do anything for
Yes, you can have up to five guilds and all of your characters are in all of them. You can choose which guild you represent at any given time and with any character. So you could join a guild that specializes in sPvP, a guild of co-workers, a guild for WvW, a social guild for missions and still be in the guild that you are in now. The only caveat is that you only earn influence for the guild you are representing at the time.
Multi-guilding in this game is fabulous.
