I recently tried getting back into developing on Ethereum and it seems that everything about my setup has changed in the last half a year. I used to just be able to download a wallet from https://github.com/ethereum/mist/releases , and be able to connect to the public testnet easily. Now even the installation guide for geth tells me how to run a private testnet, but not how to connect to the public one...
So, I got my Windows geth from https://geth.ethereum.org/downloads/ . I tried running
geth.exe --testnet --rpc --rpcapi "personal", but it doesn't appear to be synching with anything like it used to.
How can I connect geth to a public testnet, synch with it, get some ether to play around with and be able to connect to everything through a json rpc connection?
