I'd like to try your platform but when I submit the register button there is an "error 500". Looks like a little bit problem on the server-side.
I had the same case, I already used 4 different browsers. Got same result. I've been trying to login over and over again for the past couple of days and even contacted the administrator. They responded but only said they will look into it. I just hope they will fix this error soon.
Maybe try again meanwhile, yesterday Avalanche Hub layout was changed / updated, maybe login was disabled for a short time.
It will be very helpful if you disclose your total budget for this program. You are offering several tasks but you didn't describe how many tokens will distribute for each task. Please tell your budget.
It is different for each task. When signed up, you'll see how much points will be rewarded for each task (see each task description). 1 Avalanche Hub Point = 0.01 AVAX reward. Total budget is 7% (50,000,000 AVAX) for community and dev endowment (only a part is assigned to Avalanche Hub). Details: https://info.avax.network/ (point 4.1.)
