c. How do you add a signature to your post?
To add a signature to a post you must first create one via your User Control Panel. Once created, you can check the Add signature box on the posting form to add your signature. You can also add a signature by default to all your posts by checking the appropriate radio button in your profile. If you do so, you can still prevent a signature being added to individual posts by un-checking the add signature box within the posting form.
d. How do you create a poll?
When posting a new topic or editing the first post of a topic, click the "Poll creation" tab below the main posting form; if you cannot see this, you do not have appropriate permissions to create polls. Enter a title and at least two options in the appropriate fields, making sure each option is on a separate line in the textarea. You can also set the number of options users may select during voting under "Options per user", a time limit in days for the poll and lastly the option to allow users to amend their votes.
