Dear Webmasters,
I offer a unique service (for example test papers in a niche area ) free of cost to my users.
I have a database of over 60,000 such users . The trouble is that after an year most of these student would have placed themselves somewhere and the database is irrelevant to some extent outside this annual timeframe.
How best can i utilize this database without opening myself to spam emails et al.
How do you utilize the databases that you have built assiduosly . Apart from advertising for others any ideas on how to convert this into revenue specially in the field of education.
Thanks
Niko
