I am the author of CVX, a MATLAB-based modeling framework for convex optimization. The software has been the subject of at least one question here on SciComp, and has been mentioned or recommended in comments and answers by others. I'm grateful for the exposure of course but I'm also pleased that there are some genuine experts in convex optimization that regularly contribute to this forum. I intend to do so myself and I hope I acquit myself well.
When I have offered answers that involve CVX, I've made it clear I'm the author. This type of disclosure has been requested by the moderators and included in the FAQ. The policy makes perfect sense and I will certainly continue the practice.
However, for a particular forum like this---where particular computational software packages will be so frequently discussed, and where input by the authors of those packages would be so valuable---I think it would be a good idea if we can include these disclosures in our author badges.
I know that it is possible to add an additional line to our badges when we reach a certain reputation level. But I think it would be good to encourage disclosure such as this at all reputation levels. After all, authors may forget to make an appropriate disclosure in every single relevant post; but if it's in our badge, we don't have to worry.
Perhaps it would be possible to provide a tag line for a badge even at lower reputation levels---subject to peer review and/or moderator approval. Or perhaps an additional tag line could be created, perhaps again subject to moderator approval, specifically to list software packages/projects the user is involved with.
I actually thought about changing my display name to add a "- CVX" suffix just for a start, but unfortunately I'm enjoined from changing my display name again for another month.
