I am currently writing documentation and setting up a website for a open source PHP project under the LGPL - a very flexible content aggregator that for example can turn a XML datasource into a valid, cached RSS feed and much more. It was a paid project that the client has agreed to donate to the community with no strings attached.
Will it be okay to promote this in a SO post in the form of a question (what do you think about..)?
What other means of promoting an Open Source project do I have on SO?
Where do I have to apply for donated ad space on SO as proposed here?
