The help section of this forum has lots of information about rules and related information. The link is available in the bottom of this page (bottom right corner). I would like to attach screenshot but I am online using mobile phone at this moment. Alternatively, you could access it via this link: Forum Rules. Information about signature also available in this links: https://www.digitalpoint.com/help/established https://www.digitalpoint.com/help/premium
You're welcome. If you need more info, just write it here and I believe staff or other members would help answering the questions. More information about signatures: I think it is fine to use one or more sentences. A signature may consist two or more links (depend on user categories). Images or animations are not allowed because it consume much space and sometimes very annoying (plus consume much user bandwith). Fortunately it is impossible to use images/animations in signatures. A link on signature could be anything as long as it is appropriate for most peoples. DP has rules to not allow any inappropriate content. A signature also has to abide by that rules. Only appropriate content is allowed. Porn, Problematic content and any other bad things should not being placed in signature. A signature could be used to promote websites/products/services (as long as the content on the website/destination link is appropriate for most peoples). Basically, signature may contain anything as long as it is ethical and didn't break the rules (and TOS) of this forum. There are many features while creating signature (color, live link, font style, etc) and it is advised to use it wisely.
Once standard members meet eligibility requirements they may have two links in their signature, premium members may have four.
