I am interested to work on the project,
is it still open?
If I may rephrase: the work is to find given keywords in a page,
install mouse hover event to all found, valid keywords for in-text ad popup?
Also, for a rework on the in-text ad engine to be done,
could you be a bit more specific what browsers this engine needs
to be compatible: all modern browsers like firefox, opera, safari, chrome and IExplorer?
