When I go to post something, I see various Categories... what are those?

These fields represent how various entries are tied together.

Submission type is either IC or OOC, designating whether your post is an IC ("In Character") post or OOC ("Out of Character") post. Generally, blog entries are IC and forums and event posts are OOC, but you can choose either of these for your entries.

Faction is Horde, Alliance or Cross-Faction. Make sure you select the correct faction when you make a blog entry. If, for example, your blog post has Alliance-only characters, select "Alliance." If your blog entry includes characters from both factions, choose "Cross-Faction."

Players is a list of players involved in your blog. If, for example, your blog includes Pugnose, Elivel and Lorith, you'd list them out here. Please try your best to use the same names people use here for logins, just to keep things organized (in other words, you'd say "Pugnose" instead of "Pugnose Sharpaxe").

Storylines is a list of storylines that your entry is related to (typically used for blogs and events). Again, you should try your best to make sure you spell the same storyline the same way, or the software won't realize posts with those storylines entered are related. Keywords is for any other words you feel are appropriate to the entry which may help users. For example "murder" might be good if you are writing a blog about someone's murder, as might be "crimes."
