I make an offer to work on these entries. My requested funding rate is 15 XMR per hour.
I will keep a log of my time worked and provide the fruits of my labor as justification of time spent.
Let's say 105 XMR to get started, which will fund me for 7 hours of work. I imagine that I will be able to complete several Moneropedia entries in that amount of time.
If it works out, more funding can be sought.
