I worked at Connexys once upon time, but my experience was very limited to their registration software only because of that fact! However, we did have some great customer support from them as well during our first year using it (we used this system through out college). The best thing about conexsys is its ability to customize everything you need/want - so there are no limitations when choosing what features work or dont fit into whatever situation you're looking at solving!! It's been awhile since i've seen anything specific that they could improve- however if any changes were made then those would be helpful improvements overall. We had an issue where one student registered twice due to us not knowing how many students entered early enough before class started which caused issues later down the road after everyone got seated etc..
