I'm a little confused about this bounty, why do not you make a bounty that is more simple, like making google form and spreadsheet in this thread.
And even signature codes are very hard to find
Google spreadsheets do not have flexibility that the ICO Manager offers. Moreover, it is required to calculate the referral rewards automatically within the system. As for the signatures - there's a direct link with all signatures listed one after another.
If BitCointalk community finds the system too complicated we will consider options of simplifying the process of submitting the bounty activities.
We appreciate your feedback.
