With respect to the comment in another answer about more experienced users being able to answer more quickly, even if someone else has provided an answer to a question before you were able to, if you have a good answer, post it anyway. You never know when another user will find your answer more useful than the answer of a member with more reputation, and vote up you answer instead of the other. In some ways, the experience of a power Blender user can be a hindrance in forming good answers useful to novice users, either because they have become fixed in their workflows, or because some of the steps are so ingrained in their work habits that they get ignored when forming their answer, while less experienced users are sometimes more careful to include all the steps when composing their answer. Also, adding a tag to a question counts as an edit.
One way of gaming the system is suggested in another answer, but there are other ways to game the system, too. For example, having a suggested edit to another post (either question or answer) accepted gains two points of reputation, though the edit has to be more than a certain number of characters until one reaches a certain reputation. A suggested edit expanding BSE to the full form Blender.stackexchange might be useful, as new users on the site might find the acronym unfamiliar and hindering their understanding. On the other hand, correcting to to too won't work by itself to gain reputation, as the number of characters is too short. Reviewing old posts, you'll notice some with awkwardly worded titles, or common misspellings, such as using one of there, they're, or their where one of the other two is intended. A side benefit of such reviews is that you become more acquainted with the content of older questions, and will soon start to identify yourself when a post is a duplicate, or is answered by a different question which is not a duplicate.
Also, if one is a known member with sufficient reputation on another stackexchange site, joining a different stackexchange site under the same login, generally results in a grant of 100 reputation points on the new site upon joining. Finally, when you attains the reputation that earns the reputation of voting questions or answers down, use the privilege sparingly, as downvotes cost you a couple of reputation points every time they are cast.
