Of course! You can add a signature of 300 characters or less, including a signature banner image of no more than 500 pixels wide by 100 pixels high, and 30K or less. This limit applies to all images you have in total, so if you have more than one image that combined exceed the limit, we’ll have to ask that you remove them or reduce them to fit within the size limit.To add a signature, mouse over the "Conversation" button on the main menu. Click on "Forum Preferences" in the dropdown menu. There you will find your text box for entering your signature. When you have it to your liking, click “Save” and your new signature will appear on every post you make on the site! No need to create test posts… just look at any post you have already made, and it will update.
