 ## 2. Adding members to the TSC
 
-When the TSC membership is not at its maximum, a impending call-for-nominations period is agreed upon and announced in a timely manner through @OpenApiSpec on Twitter. A candidate may be nominated by through a motion by a voting TSC member in a closed TSC meeting. A nominee must not receive opposition votes of more than 25% of the TSC voting membership via a confidential vote held electronically within a week following the call-for-nominations. Approved nominees become provisional members and are expected to comport themselves as full members of the TSC during the provisional period of 4-6 weeks (to be determined at start of each nominating period), though nominees have no voting rights. The provisional period is concluded by a second, confidential vote similar to the nomination period's vote. At most there are four voting periods per year (no more than one every three months), with a minimum of one per year.
