Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
After reading these two documents I still have more questions than answers.
1. Do I need to ask Twitter/Facebook for permission?
2. Do I need to register anything anywhere? There are those "developer sections" on Twitter/Facebook, do I need to mess with them?
3. Can I use custom made buttons or maybe I have to use the buttons they provide? According to the links above, they may have some objections about custom design of the buttons. On the other hand there is so many apps and sites with custom buttons so I probably misunderstood something.
