If there is an upcoming event very soon and you already want to use the new logo in marketing material, then you should use the logo that respects the guidelines draft. But be extra strict so you will not encounter any problems in the future when certain things changes. Like not rotating the logo, use a white background, respect minimum whitespace etc.
If you respect these guidelines, I don't think anything can go wrong. If you are unsure, place a sample of your material on the wiki and put a link in this thread. That way some of us can have a look at it and see if it complies with all the points that we already discussed until now. You can find a link to the eps-type of the logo somewhere on the mailinglists, just watch out when downloading the image. The colour might be slightly changed. Make sure that the black and blue have the correct colour values. Regards, Ismaël Grammenidis
