Yes, it is allowed.
No, links are not allowed in the discussion area of questions. Links are only allowed in two places and they are either on your profile page or on the question under "Sources and Related links".
Personal websites can only be advertised on your WikiAnswers profile page. If the website is relevant to a question answer, you may post a link in the "Related Links" section of a question.However, please do not exploit the feature, as that will lead to your website being banned from WikiAnswers.
The transition from "bio page" to "profile" was made to bring WikiAnswers more in-line with its parent website, Answers.com.
You click on their profile and you'll be directed to his or her profile page, it's also called a bio page.
You can design your profile page by going to your profile, clicking "Edit this Page", selecting your background color, and then saving.
First, right click and copy the URL in the address bar of another website then click on Edit Bio, then right click and paste the link into your WikiAnswers bio page, Then save it!
To add the wiki-holic badge to your wikianswers profile page there is a link that you can copy and paste.
If you are talking about your profile page you cannot. All pages are public to others browsing the site so they can see who answered what and when.
Here, on WikiAnswers. Specifically on your own profile page.
For now, you cannot relink a different picture to your WikiAnswers account profile picture, but if you used a social networking site such as Facebook, your profile picture on facebook will be the profile picture replacing the orange guy on your WikiAnswers page. For an example, I linked my Yahoo email to my WikiAnswers account, and the picture I have on Yahoo will be the picture on my WikiAnswers profile (check it out if you want).
This is called a hyperlink, I'm afraid it's not possible unless you are allowed to post a hyperlink from Microsoft Word for example, and with it being a hyperlink already on the program and paste it in the profile page, it's not possible otherwise as WikiAnswers doesn't provide a hyperlink feature in the profile pages.
Often you can find them on their Bio/Profile page.
