Double Posting (#)
Double posting occurs when a user makes two consecutive posts, one after another. If this is done for no apparent reason, or if the posts are unimportant, double posting is looked down upon and may result in a warning or infraction for spam. You can edit any of your forum posts on GTPlanet at any time, and this is generally the best option to take if you have more to add to the discussion. However, it is not expressly forbidden, and can be useful in many cases. For example, if a reasonable amount of time has passed or you have significant information to add to the topic, present it in a new post so that others, including thread subscribers, are made aware of the update.
Thread Bumping (#)
Thread bumping is the practice of replying to a thread solely for the purpose of bringing attention to it. This is looked down upon and may result in an official warning or infraction for spam or useless posts. Your posts in a thread should contribute to the discussion or introduce new information in some way. Limited, overt bumping is permitted in The Trading Post (not to be confused with the GT5 Marketplace).
