I like that it has all my information in one place, which makes searching easier than having to look through multiple databases/sites at once! The UI could be better - sometimes you have so much info open up from different tabs or windows that its hard getting back into what your looking right now without closing everything out first then going backwards again!! Sometimes there are glitches where if someone tries something wrong they get an error when adding them rather just redirecting their browser window straight away would make things more clearcut & easygoing instead.
Good program though- definitely worth trying before deciding whether this works best suited towards how YOU work most effectively :) We use iverfy mostly because we can see who needs verification next time around by using our own internal database vs relying only off other sites' data bases etc..
