No. As per Forum backend settings, we've DISABLED the Posting as pure HTML feature, its neither enabled for Member nor for Moderator group. Reason because, allowing a member to post pure/raw HTML is a dangerous thing which can be used to inject a malicious code. Although the Forum software tries to filter some of the harmful HTML content, yet it is NOT foolproof and this tag CAN be used to steal session cookies, redirect members and destroy the topic view layout, etc.
So, yes, it's a disabled feature for now. However, members can use the RTE (Rich Text Editor), that allows them to do anything except posting raw/pure HTML content. Take some time to understand the RTE features. I'm sure you would like it.
Please elaborate with some screenshots, so we can look into the matter.
Standard edit time set for Member group is 15 minutes. They are not allowed to edit their posts after the time lapse. This is to make sure that members have the privilege to edit their content within a reasonable timeframe, yet must be restricted to keep the sanctity of their opinion.
The gender profile field has been enabled for members.
The Latest Posts feature is similar across every browser platform when using a PC or Mac. Here's the screenshot for Firefox, showing it at the sidebar as in other browsers.
