Original beta tester who couldn't afford to upgrade. It would be handy if the library checked users versions and only showed results that are compatable with the version you have. I realise that this can have a knock on effect with enticing users to upgrade, but metadata usage could be used to state for example that 45 compatable filters found (display) and 12 filters found requiring a higher version (display). I have found that you can try and download filters that won't work with your version as it isn't clear enough that they require a higher version. LOVE my version 1 FF and am grateful to you for your GAOTD offer as it is the best filter software I have used, beating the more one dimensional competition handsdown with the range of usable filters.
