Template for inviting developers

Was asked in a previous meeting to include a template for inviting new maintainers who are developers of software that we are packaging. This is a note to myself to do this. Below is some text that may work for this purpose. Thinking of adding it to the guidelines. Though suggestions and tweaks welcome.

> , just letting you know that we have added `` to [conda-forge](http://conda-forge.github.io/). This will allow users to easily install this with [`conda`](http://conda.pydata.org/docs/) ( [`conda install -c conda-forge `]( http://anaconda.org/conda-forge/ ) ). The maintenance burden here is light as all releases are built and deployed automatically with CI. Changes to how it is being built can be controlled by changing the recipe in [this feedstock (repo)]( https://github.com/conda-forge/-feedstock ). If any of you have any interest in being added as a maintainer (to make new releases for instance), we would be more than happy to add any of you to the maintainers list. Thanks for your work on this great project. 😄
