Q: Why is the background of the icons black or gray, and not transparent?
A: I guess you are using Microsoft Internet Explorer. Icons background should be transparent but support of PNG images transparency is bad in IE. I'm working on it but I recommand using an alternative free browser.
Q: Why do I get a warning message about certificate when I login?
A: The certificate is a file used to encrypt the communication between a webserver and a browser. Certificates must be signed by a "trusted entity" so you can be sure the certificate I'm sending really comes from me. Unfortunately having a signed certificate does cost money, and I signed it by myself. As I am not a "trusted entity" for your browser you are receiving this warning. You can safely accept the certificate definitively, a self-signed certificate is better than no certificate ;)
Q: What is the RSS link I have to provide to get the news from my favorite site?
A: RSS (Really Simple Syndication) is an XML file format used by some sites to help tracking news they are publishing. Search for "RSS" on your favorite news site to check if they have one. If you have no idea where to find such links, have a look to 2rss.com for a list of international news sites, and to Snyke.com for French ones.
