Hello Friends,
I know that we all are tracking our time lines through Excel Spreadsheet. I've been updating it since I took the ownership but I personally believe that It could be shared with few other users too. Hence, if anyone on this forum (this thread particularly) feels that if he/she can update and can maintain it like it has be up till now then he/she can just send me sharing request by clicking Share button (blue button) from the top-right corner of the spreadsheet.
More useful hands makes work easier.
