Although I don't have any expectations about it nor plan to actively promote it, I'm open to accepting donations and committing a corresponding amount of time per month to the free software projects listed below.

I live in Spain and, for legal reasons, to accept recurring donations I must register as self-employed (autónomo), which entails minimum costs I don't want to take on until I have reasonable assurance that I won't, at minimum, lose money each month by accepting donations.

That's the minimum I consider sufficient to make it unlikely I'll lose money each month. It's calculated by adding the estimated monthly fixed costs of being self-employed (social security contributions, taxes and administrative costs) and dividing that total by the monthly time I would pledge to community work. As living costs (for example housing) rise, minutes per € will fall each year.

I will claim pledges and start dedicating 2.99 minutes / € per month to the projects below.

Once I claim the pledges, I will start accepting requests to create Liberapay teams associated with specific project groups or individual projects listed below. That way, you can donate to a specific group or project, and I will spend the corresponding time working on that specific group or project.

I don't plan to offer that option at first. But if you're interested, contact me and we'll talk.

I'd be very surprised, but the plan is:

1. If total time (Zyte work plus community-funded free-software work) becomes too much, I'll negotiate a reduction of working time with Zyte.
2. If I left Zyte and worked only for the community, and community-funded time became excessive, I'd look for a trusted person willing to do part of the work and take the corresponding share of the money.

Go for it!
