Article requests : :Recruit people from MolBiol projects and people who list signaling as an interest on their User pages. (See Recruitment on the Talk Page).
Design a convention for drawing pathway diagrams. (See Cell Signaling Diagrams on the Talk Page).
Make sure main article of all Category:Stub-Class_Cell_signaling_articles have {{signaltransduction-stub}}. It may seem redundant to have a stub template on the main page when the project banner also lists the article as a stub, but some people into de-stubbing don't look at project pages or talk pages - just main article pages to get a list of stubs they can work on. The more ways to recruit people to help, the better.
Wikify : : WikiProject banner. Add the WikiProject banner using {{Template:Cell Signaling Project}} to the Talk Page of all applicable articles. This will help with recruiting volunteers as well as categorising articles for easy reference. (See Project Banner on the Talk Page).
Add Infoboxes or navboxes where appropriate.
Wikify internal links (wiki-links)
Improve articles by creating lead paragraphs and/or section headings.
If you do not have time to wikify, you can still assist by tagging an article for Wikification. To do this, add {{wikify}} to the top of the article.
