What websites can you advise that will help my research in up-coming ICOs?

you can surf the boards at bitcointalk.org and reddit subs for any upcoming ICOs. bitcointalk has ANN threads that announce ICOs and preICOs.
Tokenmarket, smith and crown, coins.best are all good options
They have a good list and reviews/coverage of upcoming ICOs
For forums you can try reddit ICO subs, bitcointalk.org and few FB groups
Cointelegraph and other publications also cover few ICOs
My two favorite ones are: icorating.com and icotracker.net ... a third one is under development by myself and it's called cryptoico.info
