Is there a rule on how many articles at a time?

There is no limit on how much you can write.  However, regardless of how much money you have, you can only train once per week and buy each type of equipment once per season.

Thank you! I am not yet in the bank spreadsheet so I can't really buy anything which is a bummer. But I'll keep writing articles so I'll have some cash stored up when I do get picked.
