We've definitely thought about this over the years and we may be getting closer to implementing such a system - but we're not quite there yet.
The short answer is we need more funding. Our constant financial struggle prevents us from enhancing our existing educational, conservation and research programs and creating new ones. We desperately need a sponsor with deep pockets so that we can stop worrying about keeping the program afloat and concentrate on the truly important things.
The longer answer is we are working on our tag and recovery databases when we can but it is a huge undertaking in terms of time and money to input and proofread our 11,000+ recovery records and 1,000,000(?)+ tagging records. As soon as we have a proper system in place we will certainly try to enable online data submission.
Stay tuned and if you hear of a possible source of funding for Monarch Watch please let us know!
