I think you have to realize that the website is not the highest priority at FIRST right now, you could argue that it should be, however, reality is reality.
Personally, I think it would best if we just created a list outlining specific issues, in order from most important to least, and let FIRST know, this could help alleviate some of the load. You have to realize that FIRST is a
non-profit organization, they may be a tech-based company, but they don't have the resources of a multi-billion dollar company, but they have the needs of a multi-billion dollar company(a bit exaggerated, but you get the point). Yes FIRST's website is horrid to use, yes VIMS and STIMS and TIMS are hard to use, but I don't think that FIRST has the resources to make drastic changes to those workflows, they tried to modernize it, and it failed, but they don't have the resources to do it again.
So if you really want to see changes, rather than say how terrible the website is, or complain about issues that can be annoying, start compiling them, list them by importance, maybe provide a solution, and meaningful feedback, then post it here, and email it off to FIRST, and maybe it'll get better, one small bit at a time.
Also, you people complaining about searching through unorganized lists, simple quick fix would to just use Cntrl-F and search the page for whatever you are looking for, such as a particular name, or the location of an event.
TL/DR
We get it, FIRST website is bad, fix it by making a good list of issues, provide solutions and descriptions of the problems, and then submit it to FIRST. Plus some ranty stuff
Just my 2 cents....
